SECTION 24 SAFETY LIMIT SWITCHES Safety Limit Switches Type: HLM (Die-Cast) APPLICATIONS: IDEM’s HLM range of heavy duty Die Cast Safety Limit Switches have been designed to be mounted for position sensing of moving applications e.g. guard doors, conveyors, machine beds and elevators. They are available with an extensive range of actuator heads and can be supplied with either slow break or snap action contacts. Heavy duty die cast bodies (painted red) Positive opening NC safety contact to EN60947-5-1 High mechanical life over 5,000,000 cycles Industry standard mounting to EN50041 Large choice of actuator heads available OPERATION: Operation of IDEM Safety Limit Switches is achieved by a sliding actuation of the moving object to cause deflection of the switch plungers, rollers or levers. For safety applications it is important that the moving object does not pass completely over the switch actuators so as to either cause damage to the actuator or allow it to return to its original position. CONTACT BLOCKS: Contact blocks provide positively operated safety contacts to EN60947-5-1 with optional Explosion Proof versions available. EXPLOSION PROOF MODELS ALSO AVAILABLE.
